V To all whom t mayconcern.'r

Be it known that I, PETER A. PETERSON, acitizen of the United States, residing at Omaha, in thecounty of Douglas and'State of Nebraska, have invented certain new and useful Improvements in a Dump-Wagon, of

.which the ollowingis a specification.

This invention relates to an improvement in dump dwagoiis, and has for its object to provide such a construction thatstresses occasioned by heavy loads nwill* be adequately sustained,'and that the doors may be under convenient control of an operator whok may unload or dump` theloadat one side of the vehicle before dumping at the otlierside is effected, orinay dump the entire load by one operation. Other objects of` the vinvention will be mentioned. hereinafter.

vIn the accoinpanyingdrawing Figure '1 is a plan view of a dump `wagon embodying lmy invention. Fig. 2 is a side view` of the same, the wheelsat one side of the vehicle y being removed.V Fig. 3 isfa view of the Vdump wagon in longitudinal section on line 3-3 of Fig. 1, the doorsbeing swuiigdownlwardly and the tongue being omitted." Fig.

4 is a transverse `section on linev 4 4 .of Fig.

V 1, one of the doors being swung downwardly.

Fig. 5 is aview of the front end of. the dump wagon. ig. Gis a sectional detail showing a bushingforfthe bearings of a clutch.` Fig. `2' is. an enlarged kdetail to clearly show means tolrotatea pairof miter gear-wheels for elevating the doors. l Referring now to the drawing for a more particular description,'I provide a channeliron 1 VdispOSed yat the me'dial line 'of .the vehicle, bent to lan irregular iorin yto' engage thei'ront/b'olsters '2 and the rear axle 3, and to provide a support fory the respective front and rear ends 4 and 5-ofthe body of the vehicle, suitable upright partitions 6 being `provided to which are secured the respective sidesk 7 andv 8, between'sai'd upright` partitions being provided the'convlentional recess of the front axle 10 when turning about.

According to the present construction the vvehicle bodyfis not provided with a bottom and is not obstructed except by the bolster,

the axle, partitions, and the channel iron 1 above mentioned, and the doorsV are arranged'inpairs to swing downwardly from -the channel iron from hinges 11, the pairs y of doors at the respective sides of the rear Specification of -I.'etters'1atent.

`of a pair ofl horizontal shafts 17 having bearings inbrackets 18 which are secured to the sides of the vehicle body,'chains 19 being secured to said shafts and adapted to be' wound thereon, said chains also being secured to the outer ends of. the doors; and it vwill be understood that a revoluble movement fof lthese shafts is depended upon for A elevating the doors to a closed position, and

that, for the operation of dumping, these lshafts are permitted to rotate.

Means now to be explained are provided for a control of the movements of shafts 17,

,said means for the most part being mounted upon the front end of the vehicle body. As

vbest Shown in Fig. 7, I provide a pair of stubpshafts 20 and 20', having bearings in a .sleeve 21, each of said shafts being provided at its outer end with a miter gear wheel 22, and, for causing rotary reciprocation of the sleeve, it,` is provided with an operating-lever23.,' i f K j .Y

At aand b are indicated a. pair of clutches `which are slidably mounted upon the sleeve near the lendsvthereof, eachv being provided with a slotc for receiving a lug or projection dfwhich is provided for the sleeve; and it will be understood that when the toothed clutches are in engagement with the clutchmembers or toothed hubs of the wheels 22 kanoperator, by causing a swinging movement of the lever 23 forwardly, will cause a rotatable movement of the gear-wheels 22.

Bushings 35 .are preferably employed for bearings of the clutches a and b.

Means are provided for moving each Vclutch ,into engagement with the hub of a wheel 2,2, and for causing its disengagement,

vsaid means 'consisting of. a pair oflevers24 'and 25 mounted upon and adapted to swing from a fulcrum or pin e, each lever being provded'with a pull-and-push rod f, which is 'connected with a clutch, the lever 24 preferably being pivotally mounted between its ends as best shown in Fig. 3, so that its rod f may be connected at its lower-end, tethereby cause simultaneous outward orV inward movements of the clutches when both levers 24 and 25 are movedin one direction, this being of great convenience during operation; and it will be noted that the clutches may be moved independently of each other, and that one clutch may be disengaged from a gear wheel 22 while the other clutch remains in engagement with the opposite gear wheel.

Since -the lgear wheels 22 of shafts 20 and 20' are constantly in engagement with the gear wheels 26 of the side-shafts 17, a rotation in one direction of the stub-shafts 2O land 20 will cause rotation of saidshafts 17 to cause the chains to become wound thereon for 'elevating and closing the doors, the clutches a, and b being thenv in engagement y'with the 'wheels 22, a 'downward swinging movement of -the doors during this operation being prevented by means of ratchetwheels 27 and pawls 28 best shown in Figs. 1 1 and '2, the ratchet Wheels vbeing rigidly mounted on' shafts 17 and the pawls being pivotally mounted between their ends in arms 29, kthe 'latter being pivotally mounted upon the 'sides of the vehicle box, bull-andpush rods 30 being employed and extending forwardly of the vehicle,"their rear ends being pivotallyjconnected with the arms '29, and the front end of each rod 30 being pivotally connected with an arm g of a crankshaft 31, said shafts 31 `having bearings in brackets 32 'which are fmounted upon the front end ofthe box, and each of saidshafts 31 being `provided with a pedal-arm '33.

As thus described, an operator may cause an arm 33 to swing forwardly to cause a forward swinging movement of an arm 29 for causing ldisengagement of a pawl .28 from a ratchet-wheel, this movement being-subject to the resistance of a spring 34 (Fig. 2.,).

Numerals 36 indicate brake-shoes adapted to be pressed against the rear wheels by kuse of a treadle-arm 37, which is adapted torotate a horizontalcrank shaft 38, which is mounted upon and at the front of the box, said crank-shaft 38y being provided with a push-bar 39 which extends rearwardly for a connection with the upper end of a rocklever 40 which is rigidly mounted between its endsl upon a cross-bar or shaft 41 which is disposed below and is supported by the rear axle 3, and is provided atone of its ends with la crank-arm 40. Y

Numeral 42 (Fig. 2) indicates a connecting-rod at one side of the vehicle, said rod having its front end secured to the brakeshoe, its rear end being pivotally connected with the lower end ofthe rock-lever 40, and it will be understood that the rod 42 at the opposite side of the vehicle and shown in Fig. 1 is for the same purpose, and connects the lower endof theirock-lever 40 with a brake-shoe'.

VHaving fully described construction, op-k eration willbe readily understood. The

doors maybe swung upwardly by use of the v clutches a and-b may be moved toward each, Y

other by use of the levers'24 and 25 to re lease the clutches from thefgear wheels 22, and by moving the treadle arms 33 the pawls 28 Y will be disengaged nfrom the ratchet-wheels 27, the shafts 17 thereby being free to rotate to permit the doorsy to swing downwardly to'open position.

It will be noted that the treadle-arms'33 are disposed closely adjacent to each other so that operation will be convenient for swinging them coincidently when dumping a load.- f

Among some of the advantages to be derived by use ofthe invention it 'may be stated that a containing space is provided for a load which is -greater than ordinary, dumping being provided for the entire length of the box; also by use of the channel-iron, and its form land arrangement, stresses directed to the box and doors will be adequately sustained. Also the construction ermits dumping at either side of the vvehic e, for the reason thatl the shafts 17 may rotateindepend- Vently of each other, this frequently being of Vgreat advantage when dumping the loads to doors hingeably mounted thereon adjacent Y Y to said openings, `apair of operating-shafts mounted on thevsid'e's of the vehicle body,

4each being yprovided'with agear wheel, flexible 'strands connecting the operating shafts with the doors and ada ted to be moved by a -revoluble movement -o the operating-shafts for moving thedoors into vclosed relation with said openings, ai sleeve, a pair of tubular clutch-members each circumscribing the sleeve and'having bearings in the vehiclebody,'a'pair of :gear-wheels each being provided with a clutch-member and rigidly mounted on ya 'stub-shaft in vengagement with a gear-Wheel of an voperating-shaft, means for moving the clutch-members on thef-sleeve into engagement with lthe clutch-members of the Vgear-Wheels of the stub-shafts, and means to rotate the sleeve for rotating the operating-shafts.

2. In combination With a vehicle body having openings in its bottom and having doors adjacent to said openings, a pair of operating-shafts atl the sides of said body, each being provided with a ratchet-Wheel and a gear-Wheel, flexible members connecting the operating shafts with the doors and adapted to be moved by the revoluble movement of the operating-shafts for moving the doors into closed relation with said openings, a sleeve, a pair of tubular clutch-members each circumscribing the sleeve and having bearings in the vehicle body, a air of gearvvheels each being provided with a clutchmember and rigidly mounted-on a stub-shaft in engagement with a gear-Wheel of an operating-shaft, means for moving the clutchmembers on the sleeve into engagement with the clutch-members of the gear-Wheels of the stub-shafts, means to rotate the sleeve for rotating the operating-shafts, and ay pair of paWls on the vehicle-body normally engaging the ratchet-Wheels of the operatingshafts.

3. In combination with a vehicle bodyl y having openings in its mottom `and having doors thereon adjacent to said openings, a sleeve, a pair ofclutch-members circumscribing the sleeve,4 a pair of stub-shafts having bearings in the sleeve, a pair of gear-Wheels each being rigidly mounted on a stub-shaft and provided With a clutch-member, av pair of operating-shafts having bearings at the sides of f the vehicle body, each being provided With a ratchet-Wheel and having a gear-Wheel constantly engaging a gear- Wheel of a stub-shaft, flexible members connecting the operating-shafts with the doors and movable by actuation of said operatingshafts for moving the doors into yclosed relation With said openings, a pair of handlevers each being movable for moving a clutch-member of the sleeve into engagement with the clutch-member of the gear-Wheel of a stub-shaft, said sleeve being revoluble for rotating the gear-Wheels of the stubshafts to actuate the operating-shafts.

In ltestimony whereof I have affixed my signature in presence of'tWo Witnesses.
